Applications
AWS A5.17 / ASME SFA5.17 F7A2-EL8(EL12) Single and multi-layer welding of structural steels, H-beams, ships, agricultural implements, boilers, machinery, bridges and general fabrications.
Notes on Usage
Characteristics on Usage
Insensitive to rust, scales, primers, oil and dirts on the surface to be welded. Resistance to
porosity and slag detachability are excellent. Impact value of weld metal is high.
Suitable for fillet welding of thin and medium plate with wide range of welding conditions.
As the consumption of flux is low, it is economical.
① Dry the flux at 300~350°C (572~662°F ) for 60 minutes before use.
② Pay attention to welding voltage. Excessive welding voltage causes deterioration of joint
properties.
③ Add new flux periodically to prevent the weld defects and bad bead appearance which occurs
when continuously reusing the flux.
